I don't know about other people, but the trailers I saw showed a straight forward horror film, and that's what it was for 15 minutes, then bam we had Raimi cam aplenty and an old lady trying to bite the young girl, only her teeth had fallen out. I really loved the sudden shift.

There's a scene that is very similar to Evil Dead 2 where everything,including the stuffed Deer head becomes evil...in this one we get a possessed goat!
